Will this electronic device be safe, in terms of reaching and communicating with people’s loved ones in the light, and without corruption by the interlopers?

It can be helpful for a true communication, given the imperatives of being in alignment with respect to the person reaching out, and if safety is requested by the divine so an imposter cannot be in charge of the process, giving false answers by elbowing their way in ahead of the being in the light; that must be allowed by the divine realm because of free will. We cannot police this for you if you do not do it from the human side while appreciating the hazards and pitfalls this technology would entail. This puts everyone at risk, thinking such communication is straightforward and can lead to legions of people being corrupted through manipulation if they become addicted to seeking knowledge and information, seemingly from a lofty source that is truly seeking to work against them and quite capable of doing so in a very sinister way, if people are unaware and become gullible simply wanting to connect with a loved one and will therefore be open and will make themselves vulnerable.
